I would like to use my annual report this year to address that issue, as well as some other related issues that have recently drawn public attention. The space constraints of the annual report prevent me from setting out a detailed dissertation on judicial ethics. And my judicial responsibilities preclude me from commenting on any ongoing debates about particular issues or the constitutionality of any enacted legislation or pending proposals. But I can provide some clarification on how the Justices address ethical issues and dispel some common misconceptions.

From Chief Justice Roberts’s Annual Report. So Congress can impose word-limits on the Court’s annual report. Could they impose word-limits on opinions?
